Raspberry Pi may be the most well-known board computer, but rival Orange Pi is rolling out a much larger range of boards at a furious pace and at cheaper prices.

The number of board computer users is growing, with Raspberry Pi's shipments passing 10 million units last year. Orange Pi hasn't shipped as many devices but is trying to customize its boards to meet a wider set of computing needs.

The latest board computer is the $30 Orange Pi Prime, which is almost identical to Raspberry Pi 3 in terms of features. The Orange Pi Prime has better graphics by using a Mali-450 GPU, which can process 2K video.
